Not all of the GSR headers were like that. I think it was the '00 and '01 GSR header that are the exact same length as the rest of the Integra header models. I'm pretty sure the ones you're referring to are only the 94-99 spec header. I may be off on the years, but I know that there was one incarnation that was the same length as the LS header.Because he'll have to add some piping to push the Cat forward, so it will reach the flange on the header
